kCFURLVolumeIsAutomountedKey missing, from Time Machine

when I launch mvim from the command line, then I am seeing messages throughout the day stream to the terminal that look like this:

2019-04-29 02:00:00.308 MacVim[25865:2008397] kCFURLVolumeIsAutomountedKey missing for file:///Volumes/ccc/: Error Domain=NSCocoaErrorDomain Code=257 "The file “ccc” couldn’t be opened because you don’t have permission to view it." UserInfo={NSURL=file:///Volumes/ccc/, NSFilePath=/Volumes/ccc, NSUnderlyingError=0x7fd205d05aa0 {Error Domain=NSPOSIXErrorDomain Code=13 "Permission denied"}}

2019-04-29 03:00:15.539 MacVim[25865:2016017] kCFURLVolumeIsAutomountedKey missing for file:///Volumes/timemachine/: Error Domain=NSCocoaErrorDomain Code=257 "The file “timemachine” couldn’t be opened because you don’t have permission to view it." UserInfo={NSURL=file:///Volumes/timemachine/, NSFilePath=/Volumes/timemachine, NSUnderlyingError=0x7fd2072289d0 {Error Domain=NSPOSIXErrorDomain Code=13 "Permission denied"}}

These seem to coincide time wise with when my Time Machine and/or Carbon Copy Cloner backups are timed to auto mount SMB shares in order to run backups. No idea why this would cause macvim to complain. I don't remember this happening before, but its quite annoying to have my terminal clutter up. Mvim seems to run ok otherwise.

Detailed steps to reproduce the behavior:

1. Run mvim from the command line
2. Wait for Timemachine to run a backup over network

Vim Version 8.1.950
OSX sierra 10.12.6

Inizia eseguendo mvim dalla riga di comando su macOS Sierra e riproduci l’avviso quando Time Machine o Carbon Copy Cloner monta le condivisioni SMB di backup. Traccia quale punto di ingresso di MacVim emette il messaggio kCFURLVolumeIsAutomountedKey e determina quale comportamento dovrebbe cambiare senza influire sull’uso normale. Il lavoro è completato quando gli avvisi ripetuti del terminale non compaiono più durante il montaggio dei backup e mvim continua a funzionare normalmente.
